We present the results of an expanded survey of A-shell stars using IUE high-dispersion spectra and find accreting, circumstellar gas in the line of sight to nine stars, in addition to the previously identified beta Pic, HR 10, and 131 Tau, which can

We present IUE high-dispersion spectra of the λ Boo star, 131 Tau (HD 38545), confirming the presence of shell spectral features and also providing the first detection of accreting, circumstellar gas in the spectrum of a λ Boo star. Accreting gas c

Much of the interesting physics concerning neutron stars and their evolution depends for its experimental foundation on observations of the rotation rates of pulsars. To continue recent efforts of our group in this area1–3, we began a series of pul

We report a parallax of 7.9±0.8 mas for PSR 0950+08, corresponding to a distance of 130±15 pc. The measured pulse dispersion of this pulsar implies an average free electron density of 0.023±0.002 cm-3 along the line of sight. This parallax measure

The stable rotation and sharp radio pulses of PSR 1937+21 make this pulsar a clock whose long-term frequency stability approaches and may exceed that of the best atomic clocks. Improvements in measurement techniques now permit pulse arrival times to

PSR1953+29, the second fastest of more than 400 known pulsars1, has a period of 6.133 ms and is a member of a binary system with an orbital period of 117.35 days. The system is of great interest because of what it can reveal about the evolution of pu
